To all whom it may concern:

Be it known that I, GEoncE MARK OMEGA JENKINS, subject of the King ofGreat Britain, residing at Paris, France, have invented certain new anduseful Improvements in Portable Telephone Sets, of which the followingis a full, clear, concise, and exact description.

This invention relates to a portable telephone set and more particularlyto a set of this character which is self-contained and easy of access.

It is an object of the invention to provide a telephone set which isvery compact and which can be transported to and used in locations wherespace is at a premium, such for instance as are encountered in militaryoperations. It is also an object of the invention to provide a setespecially adapted for military use in trenches or dugouts.

In order to attain these objects in accordance with a feature of theinvention, a telephone, signal device and battery are mounted in areceptacle divided: into compartments. One of these compartments is provided with means for holding a hand telephone therein in such a mannerthat it can be readily removed for use.

In accordance with another feature of the invention, a two-part cover isprovided for said receptacle, which cover may be removed as wholewithout the use of tools and which, because of a hinge joint between itstwo parts, can be manipulated to uncover either compartment of thereceptacle without uncoverin the other. The two parts of the cover areindependently secured to the receptacle by clasps which can be readilymanipulated with gloved hands, and additional securing means, in theform of straps and buckles are provided to secure one part of the coverto the receptacle.

These and other features of the invention will more clearly appear fromthe following specifications and the annexed drawings in which: 1

Figure 1 is a front section on line 1-1 of Fig. 2, of the telephone setwith the cover removed:

Fig. 2 is a side view of the same with the cover in place; and

Fig. 3 is a perspective view of the same with the cover in place.

The telephone set illustrated in the drawing embodying the inventionconsists in general ofthe receptacle 1, divided into two compartments 2-and 3 by a longitudinal partition l. The compartment 2 is divided intosub-compartments by means of the cross partitions 5 and 6. Mountedbetween the cross partitions 5 and 6 is a terminal board 7 which carriesthe binding screws 8 which serve to secure and electrically connectconductors leading from the various pieces of apparatus forming the set.In the lower part of the compartment 2 are mounted a plurality of cellsof primary battery 9 and in the upper portion is a signal bell 10 withits actuating magnet (not shown). This bell and magnet are carried bythe bracket 11, which is secured by means of screws to the partition 4.The compartment 3 is partly closed at its upper end by a transversecover plate 12. This plate is secured to the partition "l, the outerside wall 13 and upper wall 14 of the case. This cover plate forms apocket in which is adapted to be inserted the receiver end of a handtelephone 15, which includes a receiver 16 and a transmitter 17 mountedon the opposite ends of a handle. on that part of the handle portionadjacent the receiver, and on the opposite side from the receiver, thereis provided a projection indicated at 18, which projection is adapted topass under the edge of the cover plate 12 and to spring into a hole oraperture 19 in such cover provided for the purpose of holding the handtelephone in place. In order to protect the telephonic apparatus duringtransportation and when the set has been mounted for use, there isprovided a cover 20 for said receptacle. This cover is made in twoportions, 21 and 22, which are hinged together by means of a flexiblestrap 23. The cover is adapted to be placed on the receptacle in such amanner that the left-hand portion of 21 is disposed over the compartment3 and the right-hand portion over the compartment 2. In order to holdthe cover in place there is provided on both longitudinal edges of thecover, one member of a two-part clasp 24, the other member of which ismounted on the corresponding longitudinal side wall of the receptacle.In addition to these clasps there are provided on the part 22 of thecover,

straps which are secured to the top and bottom edges of the cover andcooperate with buckles 26, secured to the top and bottom sides of thereceptacles. in order to permit the set to be conveniently mounted foruse, there is provided a pair of straps aperture 29 disposed immediatelyover the bell 10 so that the bell may be heard while the cover isinplace.

While in use, and while being transported to the place of use, the coverissecured to the receptacle by means, of the four clasps 24 and thestraps 25. Upon the receipt of a. call, as evidenced by the ringing ofthe bell, the clasps 24; securing the cover portion 21 in place may beeasily opened and the telephone removed for the purpose of carryingontheconversation. This operation does not require the use of any toolsandmay be easily accomplished without the removal of gloves or mittensfrom the hands of, the user- Because of the strap which secures theother portion 22 of the cover in place, the portion 21. canbe swungabout the hinge piece 23 without in any way disturbing the portion 22.Under ordinary I circumstances it will not be necessary 1n use to removethe cover portion 22 except at long intervals. However, if it becomesnecessary to remove such portion of the cover, this may easily be donewithout the. use of any tools by opening the clasps and unfastening thestraps. i

The whole set as disclosed is particularly adapted for'use in militaryoperations and For tnis service it is necessary that the set be portableand that. access may be had thereto withoutthe use of tools and withoutthe.

necessity of manipulating complicated fastening idevices. The ordinarytwo-part l;1'lll'lk clasps such asare used for' holding the cover inplace maybe very readily 0peratcd and render access to the telephonevery easy, Furthermore, these clasps are easy to close so that there islittle likelihood of the user leaving the cover open as would be thecase if more complicated fastenings were used. The whole set ispractically moisture proof, and being made of heavy.

leather, is capable of withstanding hard usage.
